Introduction
The purpose of this document is to promote the implementation of hydrogen powered land vehicles
through the creation of performance based testing requirements for thermally activated pressure
relief devices for compressed hydrogen fuel containers. The successful commercialization of hydrogen
land vehicle technologies requires standards pertaining to fueling stations, vehicle fuel system
components and the global homologation of standards requirements for technologies with the same
end use. This will allow manufacturers to achieve economies of scale in production through the ability
to manufacture one product for global use.
This document is based on the CSA Standard ANSI/CSA HPRD 1-2013.

4 Service conditions
4.1 General
Fuel containers may accidentally be exposed to fire or elevated temperature. These conditions may act
to increase the contained pressure or to degrade the structural materials, depending on the container
type and materials of construction. A pressure relief device provides a means to vent the fuel container
under these conditions.
A specific pressure relief device may not be suitable for all container types, sizes or installations. Fuel
container or installation standards may require that a pressure relief device be tested in conjunction
with other components.
CGA S1.1 states: “relief devices may not prevent burst of a cylinder under all conditions of fire exposure.
When the heat transferred to the cylinder is localized, intensive, and remote to the relief device, or
when the fire builds rapidly, such as in an explosion, and is of very high intensity, the cylinder can
weaken sufficiently to rupture before the relief device operates, or while it is operating”.
The following service conditions are representative of what can be seen in an automotive service.
These service conditions are provided as a basis for the design, manufacture, inspection and testing of
pressure relief devices which are used in compressed hydrogen vehicle fuel containers.
4.2 Design service life
The design service life of the pressure relief device shall be specified by the pressure relief device
manufacturer.
4.3 Nominal working pressure
This document applies to pressure relief devices that have a nominal working pressure, as specified
by the manufacturer, of 25 MPa, 35 MPa, 50 MPa or 70 MPa at 15 °C, hereinafter referred to in this
document as the following:
a) “H25” — 25 MPa;
b) “H35” — 35 MPa;
c) “H50” — 50 MPa;
d) “H70” — 70 MPa.
Other nominal working pressures for hydrogen gas besides those defined are allowed if the required
qualification test requirements of this document are met.
4.4 Durability test cycles
The design pressure cycles for pressure relief devices shall be between not more than 10 % of the
manufacturer's specified nominal working pressure and not less than 150 % of the manufacturer's
specified nomina
